Electrical Requirements for a 4 ton Acadia Air Handler
This is mind boggling!
I have a customer interested in installing the Acadia heatpump in his house and he is requesting the electriocal requirements for the Air Handler and 15k resistance heater. I told him 40 amps 220volt but when I called Hallowell to confirm this I was told that the requirements for the variable speed AH with the 15k resistance heater is 90 Amp!!!
When I expressed my astonishment they told me their air handler is a York Generic variable speed.
Can it possibly require 90amps?
yes,if you used 10kw you would only need 60 amps
I'd say any 15 kw air handler out there would require 90 amp single circuit or 60 & 30 for dual circuit.
15 KW/240 volts = 62.5 amps
62.5*1.25(continuous load duty circuit protection factor)=78.125amps circuit protection.
Add on 3.5 amps for the 1 horse power VS motor. You need just over 80 amps total.
So a 90 amp breaker.
Or 1-30 amp, and 1-60 amp.
